…disk exists A USB audio interface that exposes its driver files as a small disk enumerated as /dev/sda ahead of the NVMe, so a single-disk deploy with no Host Primary Disk wrote to it and sgdisk refused every partition as too big for the disk (fogproject #778). getHardDisk() now puts USB-transport and removable devices at the back of the pool and leaves them out of the automatic choice, whether that is first-enumerated, largesize=1 or smallsize=1, unless they are the only disks present. Host Primary Disk still matches them by name, so a deliberate USB target keeps working. tests/checks/primary-disk-dedup.sh gains a USB device enumerated first and cases for each rule.

For FOGProject/fogproject#778. Stacked on #175, since both change
getHardDisk()and its harness; it retargets to master when #175 merges.The reporter's screenshot shows the deploy going to
/dev/sdaon a machine whose OS disk is NVMe, with sgdisk refusing every partition as too big for the disk. That/dev/sdais the Focusrite Scarlett's USB storage, which exposes its driver files as a small disk and enumerates ahead of the NVMe.getHardDisk()now puts USB-transport and removable devices (lsblk TRAN=usborRM=1) at the back of the pool and leaves them out of the automatic choice, whether that is first-enumerated,largesize=1orsmallsize=1, unless they are the only disks present. Host Primary Disk still matches them by name, so a deliberate USB target keeps working, and a machine whose only disk is USB or an SD card still images.tests/checks/primary-disk-dedup.shgains a 32 GB USB device enumerated first and cases for each rule: never chosen automatically, last in the pool, matched by name, chosen when alone. Five of eight cases fail on the old code.🤖 Generated with Claude Code
